Now that atomic_t is a generic opaque type for all architectures, it is
unwise to use intimate knowledge of its internals when manipulating it.
Instead of relying on the "counter" member being at offset 0 from the
beginning of an atomic_t, explicitly reference the member. This guards
us from any changes to the layout of the beginning of the atomic_t type.

This follows the sparc changes a439fe51a1.
Most of the moving about was done with Sam's directions at:

with subsequent hacking and fixups entirely my fault.
